More Great America Preparation and Reminders!

We discussed making measurements at Great America as well as what to do and NOT do while you are there.  The remainder of the period we worked on physics projects.  Reminders:

School Arrival Time: 7:45 on front steps Buses roll at 8 am
Please ride on your assigned bus.
     Period  1, 2 3(Bronec and Borrison) = Bus 5
     Period 3, 4 (A-Vanderhaegen)= Bus 6
     Period 4 (Variot-Zicovich)= Bus 7

Leave Great America at 2 pm; buses are loaded by 2:15 pm; buses roll at 2:30 pm

Make sure you remember to bring: Great America packet, astrolabe, pencil, calculator, timing device.

HW: Project rough drafts due next time!

More Great America Prep

We continued our preparations for Great America by learning how to make measurements while at the park and reviewing the energy transfers involved in roller coasters.  We watched this great episode Newton's Apple:

HW: Great America Review Sheet

Modern Marvels- Roller Coasters periods 1,3 only

Since so many students were taking the AP English Language test we didn't do much in class.  I passed back project proposals and discussed projects that were rejected.  We also watched the Modern Marvels episode on Roller Coasters

Green WS (Class Set) and Triangulation Lab - Mr.B.

Triangulation

We began our preparation for Great America by constructing and learning how to use an astrolabe.

HW: Finish lab

Physics Project Introduction

I introduced the physics project and showed sample projects for most of the period.  I allowed people in class time to begin brainstorming their ideas.

HW: Proposal due next time!
